Answer

Explanation:

Step1: Analyze Equation A and B

Equation A: (3(x + 2)=18). If we divide both sides of Equation A by (3) (a non - zero constant), we get (\frac{3(x + 2)}{3}=\frac{18}{3}), which simplifies to (x + 2 = 6\neq18). Wait, no, actually, if we consider the wrong operation assumption (but for the sake of the problem's options), if we assume a wrong division (but in reality, the correct way to get from (3(x + 2)=18) to (x+2) is divide by 3, but here in the problem's context of the options): If we consider the general rule of equation transformation. For an equation (a=b), if we do (a\div c=b\div c) ((c\neq0)), it's a valid transformation. In Equation A (3(x + 2)=18), if we divide both sides by (3) (a non - zero constant), we get (x + 2=6) (but in the problem's options, maybe a mis - write in the problem's Equation B, assuming the intended operation is dividing both sides by a non - zero constant to transform the equation structure).

Step2: Check for equivalent equations

Equation A: (3(x + 2)=18), solving (3x+6 = 18), (3x=18 - 6=12), (x = 4). Equation B: (x + 2=18), solving (x=16). Since the solutions are different ((x = 4) for A and (x = 16) for B), they are not equivalent.

Answer:

  1. A. Multiply/divide both sides by the same non - zero constant
  2. B. No
